Designing and building the RS-485 transceivers, writing some test code …
↓↓↓ Complete description, time index and links below ↓↓↓
Last time we did some housekeeping in regards to our hardware and software, during which we discovered a fatal design flaw (link below). But before we tackle that problem (I have to think about it), let’s implement the RS-485 communication.
We start with a recap of our communication structure. Then we make a number of decisions regarding our bus design. After choosing a suitable transceiver chip, we build the circuitry, set up a dummy master, and write some code to test everything.
00:00 Intro – let’s start with the RS-485 stuff
00:38 Recap – everything communicates via RS-485
02:36 RS-485 hardware design – four decisions to make
09:41 RS-485 transceivers – Chipanalog CA-IS3098W
18:19 Circuit – transceiver, 2 resistors and 6 capacitors
20:21 Breadboard – almost the same for master and slave
22:04 Code – for master and slave (fly-by-wire outboard)
29:19 Test – works, some transmission errors though
32:01 Wrap-up – next is implementing the protocol, bye
